Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 939490, here are decompositions:

3 + 939487 = 939490
47 + 939443 = 939490
59 + 939431 = 939490
113 + 939377 = 939490
131 + 939359 = 939490
173 + 939317 = 939490
191 + 939299 = 939490
197 + 939293 = 939490

Showing the first eight; more decompositions exist.
